Errors in both registration and segmentation

[FS-1983]

After fixing the eroor message as posted in my other issue from today, I tried to use the tool again. I'm on Win10 using slicer 5.0.3.
After running, there is now a cropped copy of the fixed volume. From processing, this is the parse:

Now, when I try to use the segment, I get a different error message:

Again, thanks for any help!
